As you can see it looks a bit classic styled. The background color has been changed along with some minor UI changes.

UPDATE 9:

The latest Firefox 4 Beta 5 Preview build features a new redesigned "App" button in titlebar which looks as following:

[attachment=31p785gl]Mozilla_Firefox_4_App_Button_Redesigned.png[/attachment1p785gl]

As you can see it features Cut/copy/paste buttons in menus similar to Google Chrome developer builds.

Also the "App" menu has been divided into 2 sub-menus which allows Firefox developers to put more menu items than before.

UPDATE 8:

Mozilla has compiled final build of Beta 4 and started working on Beta 5 build. Download links are given at the end of this topic.

UPDATE 7:

The latest Beta 4 Preview build features 2 new additions:

* Tab Sets (formerly known as Tab Candy)
* Firefox Sync

To invoke "Tab Sets", simply press "Ctrl+Space" keys together. You can also drag-n-drop its button to standard toolbar using toolbar customization window.

"Sync" has also been included in the build so you no longer need to install it using external add-on.

UPDATE 6:

Mozilla has compiled final build of Beta 3 and started working on Beta 4 build. Download links are given at the end of this topic.

UPDATE 5:

The latest Beta 3 Preview build adds a new option to enable / disable tab previews in Windows Taskbar in Firefox Options page:

UPDATE 4:

The nightly build features "App Tabs" option which puts the tab to the left of Tab bar. It also shrinks the size of the tab and only shows the favicon to save the Tab bar space.

To convert a tab into "App Tab", right-click on the tab and select "Make into App Tab" option.

To make it normal, again right-click on the tab and select "Make into Normal Tab" option.

UPDATE 3:

The Titlebar "App" button glitch, which we mentioned earlier, has been fixed in the latest Alpha 6 Preview build.

PS: A new glitch found! Double-clicking on Tab bar should create a new tab but now it maximizes / restores browser window which is incorrect behavior.

UPDATE 2:

Mozilla has again updated the UI of its upcoming web browser Firefox 4.0 (which is still named as 3.7 in testing builds) in the latest Alpha build.

The new "App" button has been moved to Titlebar which saves space and also "Tabs on Top" option has been enabled by default so the Tab bar is shown on Top by default.

There is some glitch btw. When you maximize the window, the "App" button doesn't look properly. Since its an Alpha build and the work is in progress, the glitch will be fixed in future builds.

UPDATE 1:

The latest Mozilla Firefox 3.7 Alpha 5 Preview build comes with a new Add-ons Manager as shown in following screenshot:

[attachment=01p785gl]New_Firefox_Add-ons_Manager.png[/attachment1p785gl]





The most noticeable change is, it doesn't open in a new dialog box. Instead it opens in a new tab in the same browser window.

It shows a better organized interface compared to the old one. The fonts size has been increased for better readability.

Overall its a nice change and makes the browser more user-friendly.
